Rapid urbanization, increasing prosperity, economic development coupled with changing lifestyle has produced a tremendous generation of waste in huge quantity. The dumping of this huge quantity of partially segregated waste has become a public health and environmental concern. According to an estimate, more than 9500 tons per day (TPD) of MSW (Municipal solid waste) is generated in Delhi and about 60% of waste is transported to these three-active landfills in order of maximum in Bhalswa followed by Ghazipur and Okhla landfill sites which are non-scientific landfill and less than 40% were transported to composting plant and waste to energy plant. These waste dump sites have finished their commissioned date and crossed the permissible height and come under matured landfill (old). Dumping of unsegregated waste in these landfills contribute long-term threat to groundwater as various parameter such as inorganic, organic and heavy metal liberate from leachate of unsegregated solid waste and concentration varies with season. Soil contamination, air pollution and various other environmental, health and social impacts in the vicinity of these landfills are found to be connected with uncontrolled dumping of waste. The study reported that, till date in Delhi, there is no single landfill which is controlled and provides with baseliner or proper cover. All three active landfill still received solid waste beyond their capacity without any attention to waste segregation. Impact of landfill leachate on groundwater revealed by presences of high concentration of various parameters like Chloride, Nitrate, Sulphate, Ammonium, Phenol, Iron, Zinc and Chemical oxygen demand in assessed which showed that quality of groundwater is significantly affected by the percolation of landfill leachate. The main problem of the landfill is the generation of toxic leachate and gases which finally end their life in groundwater and environment and ultimately reach to human and damage aquatic life present in water. On the other hand emission of greenhouse gases lead to the risk of fire and also cause global warming. Presently NGT had warned officer of these three landfills of Delhi to remediate landfill. There is an urgent need of leachate collection system and treatment facilities and gas trapping technologies at this landfill for energy generation and to protect the contamination of groundwater.

A liquid which drained or leaches through the waste at a landfill site is known as leachate. Leachate from a landfill varies widely in composition depending on the age of the landfill and the type of waste that it contains. It can usually contain both dissolved and suspended material. This study concentrate on the composition of various parameters of leachate collected from a highly saturated sanitary landfill sites at Bhalswa, Delhi. it has been found that Bhalswa landfill leachate have highest concentration of different parameters such as total dissolve solid, total solid and electrical conductivity i.e., 9890 mg/l, 12580 mg/l and 14892 mho/cm respectively. These results will be helpful in future for determination of expected impact on ground water and biodiversity due to generation and percolation of leachate. This study will also be helpful to deal with the possible low cost treatment methods.

Rapid population growth of major urban centres in many developing countries has created massive landfills with extraordinary heights and steep side-slopes, which are frequently surrounded by illegal low-income residential settlements developed too close to landfills. These extraordinary landfills are facing high risks of catastrophic failure with potentially large numbers of fatalities. This study presents a novel method for risk assessment of landfill slope failure, using probabilistic analysis of potential failure scenarios and associated fatalities. The conceptual framework of the method includes selecting appropriate statistical distributions for the municipal solid waste (MSW) material shear strength and rheological properties for potential failure scenario analysis. The MSW material properties for a given scenario is then used to analyse the probability of slope failure and the resulting run-out length to calculate the potential risk of fatalities. In comparison with existing methods, which are solely based on the probability of slope failure, this method provides a more accurate estimate of the risk of fatalities associated with a given landfill slope failure. The application of the new risk assessment method is demonstrated with a case study for a landfill located within a heavily populated area of New Delhi, India.

Methanogens, a key contributor in global carbon cycling, methane emission, and alternative energy production, generate methane gas via anaerobic digestion of organic matter. The methane emission potential depends upon methanogenic diversity and activity. Since they are anaerobes and difficult to isolate and culture, their diversity present in the landfill sites of Delhi and marshlands of Southern Assam, India, was analyzed using molecular techniques like 16S rDNA sequencing, DGGE, and qPCR. The sequencing results indicated the presence of methanogens belonging to the seventh order and also the order Methanomicrobiales in the Ghazipur and Bhalsawa landfill sites of Delhi. Sequences, related to the phyla Crenarchaeota (thermophilic) and Thaumarchaeota (mesophilic), were detected from marshland sites of Southern Assam, India. Jaccard analysis of DGGE gel using Gel2K showed three main clusters depending on the number and similarity of band patterns. The copy number analysis of hydrogenotrophic methanogens using qPCR indicates higher abundance in landfill sites of Delhi as compared to the marshlands of Southern Assam. The knowledge about “methanogenic archaea composition” and “abundance” in the contrasting ecosystems like “landfill” and “marshland” may reorient our understanding of the Archaea inhabitants. This study could shed light on the relationship between methane-dynamics and the global warming process.

Exponential population growth, unprecedented urbanization and changing life style has led to the substantial generation of municipal solid waste. Approximately only 20 percent of the waste generated is processed and remaining 80 percent is dumped in to landfill sites. Delhi is generating highest quantity of per capita municipal solid waste and about 28 million tonnes of waste lay at Bhalswa, Ghazipur and Okhla landfill sites.This waste have high calorific value and has lot of potential to convert into compost and energy for human use.There is an urgent need to find sustainable solutions and appropriate technology to better manage waste and to generate energy from the waste.The aim of this paper is to characterization the waste and to analyze the waste energy generation potential of municipal solid waste from South Delhi

Municipal solid waste (MSW) dumps are widespread, and their numerous hazardous materials pose a serious threat to the environment and the local population. Leachate, which seeps into the porous ground surface after waste is dumped in a landfill, can contaminate groundwater. Such leachate makes groundwater and the associated aquifer unsuitable for houses water supplies and other uses. In the present study, five leachate samples are collected around Bhalswa landfill, and ten groundwater samples are collected between Bhalswa landfill to Delhi technological university at random distances of 366.82 m, 443.14 m, 557.09 m, 557.09 m, 679.07 m, 2890 m, 3220 m, 3510 m, 3630 m, 4240 m and 4290 m for physicochemical analysis of leachates and groundwater. This physicochemical analysis includes parameters like pH, total dissolved solids (TDS), alkalinity, sulphate, nitrate, electrical conductivity, chloride, and phosphate and the results obtained for groundwater are compared with the BIS code of drinking water to know whether groundwater is suitable for drinking or another domestic purpose.

The disposal of waste from anthropogenic activity has been done by landfilling for centuries. This technique of waste disposal provides an efficient and cost-effective methodology of the urban waste elimination. However, this technique suffers from many imperfections such as odour, biogas, and especially leachate. Field studies carried out by researchers proved that solid waste leachates may migrate to superficial water, even in landfills with geotextile protection at the base. These contaminants can percolate to greater depths. Consequently, it is necessary to control compacted soil layers to prevent the advance of contamination front as well as the effect of leachate to soils that are exposed to pollutants. In this study a physiochemical analysis is done of soil samples around Bhalswa Landfill near Rohini (Delhi), which is based on parameters like pH, total dissolved solids (TDS), alkalinity, chloride content, total hardness, calcium, magnesium content of soil in liquid form and other parameters from centrifuged sample of soil to find content of sulphate, nitrate and phosphate. At present 10 soil samples are collected between Bhalswa Landfill and Delhi Technological University. Some samples collected had pH of 8.0-8.2 which shows that soil is alkaline. The results obtained are compared with the virgin soil samples in DTU area so as to understand the horizontal variation of physiochemical parameters of soil and comparison with the standard range of chemical contents in soil.
